`l Beit known that I, E. C. BENYAURD, of

the cityof Philadelphia and :State of Penne sylvania,haveinyented a new and usefull Safe "Catch forj "Breastpins, "Cuff-Pins," Chatelaines, and otherPieces of Jewelry Rei quiring` a Catch; `and Ido hereby declare that the followingisa full, clear, and exact description of the construction and operation of the same,y reference being had to the annexed drawings, making a part `of lthis specificatiominwhich- Figure l, is a perspective view` (enlarged) of the catch applied to a `common breast pin 5, Fig. 2, -aplan view of thesame; Fig. 3, a a longitudinal sectionyFig `t, a like section,

"lso

The` nature of my` invention consists in constructing f and combining together" twol slotted cylinders, the one within the other,-

the outer one beingsoldered to the backof a `piece of jewelry, `with its slotted side up-e and the inner `cylinder fitting nicely within `the outer one `so asto be capable ofbeing "a so as to hold the `point end o'f the i pin as berotated therein by means of `a thumb-andfinger piece fixed thereto-so that the `point` end of the pin proper, of the piece of jewelry may be` admittedforfreleased, at pleasure, "through the slotswhenthey are matched or brought together; andbe held securely and safely when the Iinner cylinder is rotated half round,` or turned so as tofclose the slot in the outer cylinder.

Referring tothe drawings, A; is the safe-`A` catch, attached toa common breast pin (B) fore stated`-this catchiiscomposed of three `pieces-as follows-an outer "cylinder (a);

an inner cylinder ("6), adapted to fit so as to be capable of being rotated `within the outer f one; and a thumb-anddinfger i piece (0),`

soldered to the outer end o the inner cyl-` inder. Figs. 7 and 8, represent the two first named pieces as they are cut previously to their being formed up, and Fig. 9 the thumb-and-inger piece, previously to its beone (Fig. 1l) having a flange ('cZ,) turned outso as to keep it within the outer one, when so placed, by bearing against its inner end-but, in constructing the catch, I find it most convenient to turn this flange after the piece is inserted in its place within the outer cylinder, as it need not project beyond the surface of the outer cylinder. The slots (e e). are both cut about twothirds the length of the cylinders, `commencing at the inner end thereof, and wide enough to admit the passage of the point end of the pin proper, freely through them, into,

scribed and shown in the drawings, it will be readily perceived that if the point end of the pin proper is pressed down through the slots in the two cylinders, when the slots are thus brought together, and the inner cylinder then turned (by the thumb and finger piece) half roundthat the point end of the pin will be safely secured within the inner cylinder; and that'if it is again turned half around, the two slots being thus again brought together, the point end of the said pin will be released-and when the said pinis made so as toy spring on its shoulder at thejoint, as usual, when the slots are brought together as before stated the pin will spring out in the position shown in Fig. 4.! t

As the size of the different pieces described` will.` be governed by the particular pieceof jewelry to .which the catch is to be applied, it will not be necessary to specify on this point-butto state generally that 'this catch can be conveniently made of any of the metals commonly used for such purposes, and applied to any piece of jewelry requiring a catch, so as to be more neat, convenient, and less liable to get out of order ing soldered to the inner cylinderFigs. 10, and: ll represent the "two: cylinders as formt-3d, when united together-the inner than any heretofore known or used-While at the same time it is best adapted for the purpose, being simple, easily constructed, durable and perfectly eHectual as a safecatch for jewelry.

Having thus, in full, clear and exact terms, described the construction and operation of my invention, and pointed out its utility and novelty, I proceed to state that I do not claim the application of a safe catch, generally, for the purpose of holdin the point end of the pin of a piece o? jewelry-But E.
